Memorization Load

Modeling blindfold memorization as an information-theoretic load: the log2 of the number of distinct visual states of the puzzle a solver must be able to tell apart to reconstruct it. Only solved (non-DNF) solves count; DNS/DNF attempts contribute nothing. For 3x3, 4x4, and 5x5 this is a fixed number of bits per solve; for MBLD, each successfully solved cube within an attempt counts as one 3x3-equivalent solve.
